My only advice would be to exercise the hinges on this company and slam the door shut and shop elsewhere.
Quick enough to take your money not so quick to rearrange a new delivery after they cancelled the first one which was four days and not next day customer service is lackluster as much use as a chocolate fireguard. Keep clear I'm now in the process of taking this company to trading standards not only have I not received my door that was paid for nor a refund nor an explanation but to top it all I've had to purchase another door this time from a reputable company and fit it for free at the customers home.
A very disgruntled Tradesman.
